Abstract
In order to measure moisture-concn. profiles, a method based on neutron transmission was applied. Drying curves and diffusion coeffs. were calcd. from these profiles. The diffusion coeffs. appeared to be similar to the diffusion coeffs. detd. by comparing the numerical soln. of the diffusion equation with exptl. drying curves. The accuracy of both methods is about the same. Because the moisture concn. profiles are flat at high moisture concns., the accuracy of the calcd. diffusion coeffs. at high moisture concns. is not as high as is obtained at lower moisture concns. The neutron-transmission-based method is reproducible and has the advantage that it is not necessary to assume a certain relation between the diffusion coeff. and the moisture content.
